WATER-CLOSETVALVE.

SPECIFICATION forming part of Letters Patent No. 285,191, dated September 18, 1883.

Application filed October 31, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, PETER Wnrrmof St. Louis, Missouri, have made a new and useful Improvement in Water-Closet Valves, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure lis alongitudinal section, the valves being closed; Fig. 2. a similar section, the valves being open; Fig. 3, a side elevation, partly in section, the View being taken from the opposite side to that of Figs. 1 and 2; Fig. 4, a top view of the main-valve chamber, the cap being removed; and Fig. 5, across section taken upon the line 5 5 of Fig. 3.

The same letters of reference. denote the same parts. I

The present invention relates partly to the means for limiting the movement of the main valve and partly to the mode of operating the relief-valve.

Referring to the drawings, A represents a valve embodying the present improvement.

B represents the chamber of the main valve.

0 represents the inlet to, and D the outlet from, the valve. E represents the main valve, seating downward at e. The valve-stem E is provided with the cup-leathers F, G, and H.

I is a plug screwed into the cap J of the chamber 13, so as to come above the top of the valve-stem E. This plug serves to limit the movement of the valve E. When it is desired to have thevalve E open wider, the plug is screwed upward in the cap, enabling the valve-stem E to rise higher in the' valvechamber, and when it is desired to shorten the movement of the valve E the plug I is K is the passage in the shell b of the valvechamber B, through which the main waterpressure passes from beneath the valve-seat e to above the cup-leather G, the inlet to such passage being at It, Figs. 1, 2, 3, and the outlet therefrom being at k, Figs. 2, 3, 4.

L is another passage in the shell 1), leading from the valve-chamber B above the cupleather G to the chamber M, in which the relief-valve N is contained.

0 represents the float-lever. The float is not shown, as its construction is well understood, the float being such as is ordinarily used in water-closets, and similar to that shown in Letters Patent previously granted to me, saving as modified to enable it to operate the relief-valve, as hereinafter described. The lever is pivoted at 0, and the end 0 of the lever engages in the ordinary manner in the slot e of the valvestem E. There is an offset at 0 in the float-lever, and when the float falls the offset 0 encounters the stem n of the reliefvalve N, causing the valve N to be lifted from its seat at. The water then flows-from above the cup-leather G through the passage L into the chamber M and past the valve N to without the valve, relieving the pressure above the cup-leather G. The float-lever, continuing to fall, operates to lift the valve-stem E and to unseat the valve E, bringing the parts into the position shown in Fig. 2. In closing the valve E, the water having lifted the float, the water-pressure operates first to close the relief-valve N, after which the main valve E is seated. The cup-leathers G and H confine the water in the portion B of the valve-chamber, and the cup-leather F prevents the water from passing above the outlet D. The plug I is also'furnished with the cup-leather I, for the purpose of packing the plug. A suitable cap, I, serves to inclose the plug I and to complete the valve at the top. By means of the passage e the water-pressure above and below the cup-leather H is equalized, the water, in seating the valve E, passing upward through the passage 6' to above the stem E.

I claim 1. The combination of the valve A, having chamber B, provided with the passages L K, the valve E, the stem E, the cup-leathersFG, and the relief-valve N,with the float-lever 0, having the offset 0 substantially as described.

2. The combination, in a water-closet valve having chamber B, provided with passages L K, of the valve E, the stem E, the cup-leatL- ers F G, the cap J, the plug I, the relief-valve N, and the float-lever 0,. substantially as described.

3. The combination of the valve A, having chamber B, the stem E, having the passage 6', and the cup -leather H, substantially as described.

4. The combination of the valve A, having chamber B, the cap J, the stem E, and the cup-leather H, substantially as described.
